Title: Temperature detector and sampling device
IPC: G01N1/12
Filed: 1966-01-25
Abstract: 1,118,062. Withdrawing samples of charges. ELECTRO-NITE CO. 25 Jan., 1966 [12 April, 1965], No. 3341/66. Heading F4B. [Also in Division H1] Apparatus for simultaneously detecting the temperature of, and obtaining a sample from, a bath of liquid such as molten steel or copper comprises an expendable thermocouple unit attached to one end of a tube 12 of heat insulating material and a sampling vessel 64 mounted at the same end of the tube and substantially parallel to the longitudinal axis of the tube, the vessel being surrounded for the major portion of its length by a heat insulating body 46. The thermocouple comprises wires 18, 20 made respectively of platinum and platinum-rhodium and disposed in a refractory tube 22 embedded in refractory cement 16 in the end of the tube 12, the wires 18, 20 being connected respectively to an alloy wire 24 (98% copper, 2% nickel) and a copper wire 26 to form cold junctions 27, 29 embedded in the cement. A connector 28 made from polymeric plastic is also embedded in the cement and is adapted to cooperate with a receptacle inserted from the free end of the tube. The vessel 64 is made from a vitreous or ceramic material such as quartz and consists of an evacuated tube lined with aluminium 70 and sealed at one end by a button 68 fusible at a much lower temperature than the vessel. The heat insulating body 46, which surrounds both the vessel and the thermocouple unit, is a non-rotatable force fit on the end of the tube 12, and its forward end is surrounded by a tape 76 forming a well for refractory cement 78 which protects the end 14 of the tube and retains fusible caps 38, 72 covering the ends of the unit and the vessel. In use the apparatus is immersed in the bath for between 3 and 10 seconds, during which time the temperature is recorded and fluid flows into the vessel and partially solidifies. The apparatus is then withdrawn, broken open to obtain the sample, and discarded. In a modification, for use in baths without a slag layer, the vessel is inverted and may be open at the top so that the liquid flows in under gravity.

Title: Weight and pressure operated well testing apparatus and its method of operation
IPC: E21B34/10
Filed: 1976-01-28
Abstract: 1514852 Wells etc. HALLIBURTON CO 28 Jan 1976 [14 July 1975] 3385/76 Heading E1F A valve 24 in a well testing string is opened by increasing the pressure in the well bore annulus, the pressure acting on a piston 44 formed on an operating mandrel 40, until the pressure differential across piston 44 is sufficient to overcome the weight acting on the mandrel 40, thus raising the mandrel 40 to open the valve. As described the test string includes a telescopic sliding joint 20, drill collars 21, the weight and pressure operated valve 24, a delayed action weight operated valve 25 and a packer 27. The packer 27 is set with the sliding joint 20 partially collapsed (Fig. 3) so that the weight of the string above the joint 20 is supported by the blowout-preventors (not shown), the only weight acting on the valves 24 and 25 being the weight of the drill collars 21. The sliding joint 20 also accommodates the movements caused by the operation of the valves 24 and 25. In use the string is run into the well with valve 25 closed and valve 24 open (Fig. 2). The packer 27 is then set and the weight of the collars 21 acts on the operating mandrel 40 of valve 24 to close the valve 24 (Fig. 3). During this movement of mandrel 40 a piston 44 on the mandrel 40 moves downwardly in a sealed chamber 42 to create a pressure differential across the piston 44. The weight of the collars 21 also acts on valve 25 to open the valve (Fig. 4) after a time delay (determined by the movement of a metering piston 54 in an oil filled chamber 53). Any subsequent increase in pressure in the well bore annulus acts on the bottom of piston 44 through ports 45 so that, when the pressure differential across piston 44 is sufficient to overcome the weight of the collars 21, the operating mandrel 40 is raised (Fig. 5) thus opening valve 24. Formation fluid can then flow up the test string. The valve 24 is closed by returning the annulus pressure to its original value. For Figures see next column

Title: Improvements in and relating to electrostatic vibratory devices
IPC: H04R19/02
Filed: 1940-02-23
Abstract: 537,554. Electrostatic instruments. SHORTER, D. E. L., and MAYO, C. G. Feb. 23, 1940, No. 3477. [Class 40 (iv)] Movement of the vibratory electrode of an electrostatic instrument causes variation of the polarizing field tending to restore the electrode to a normal position of equilibrium whereby mechanical restoring force may be reduced or rendered unnecessary. As shown, the instrument comprises .a plate electrode B vibrating between two fixed electrodes A, C, the condenser BC being arranged in the anode-cathode circuit of VI which includes resistance R1 providing negative feed back to stabilize the output A, C. The valve V1 is supplied with a supersonic control voltage E1, and resistance R1 is shunted bv an inductance L4 to avoid feed back of audio-frequencies. The output voltage is applied over condenser C2 to rectifier W, the resulting D.C. potential across R3 being used to bias the polarization control valve V2 negatively, The circuit constants are such that the output and A.C. biassing voltages are directly proportional to the spacing of electrodes B, C. When electrode B approaches C, the negative bias on V2 causes the potential of electrode B to decrease and the potential gradient from A to B to increase thereby tending to restore the electrode, the opposite effect being produced when B approaches A. Chokes L2, L3 reduce the load on valve VI due to V2 and the instrument capacity. When used as a loud-speaker, signal voltages are applied at E2 or E<SP>1</SP>2 but the device may also be used as a microphone. As the loud-speaker will tend to respond uniformly to all frequencies, the signals may be equalized to compensate for variation of acoustic radiation with frequency. The vibratory electrode may be of light aluminium foil. As shown in Fig. 2, it comprises a diaphragm with longitudinal corrugations D terminating in transversely corrugated edges F secured in clamps G. The control voltage may alternatively be varied in frequency or phase by the vibrating electrode.

Abstract: 825,208. Solvent extraction. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 28, 1957 [Feb. 4, 1956], No. 3563/56. Class 81 (1). In a batch solvent extraction process, a mixture A, B to be separated into its components is dissolved in a solvent W, Fig. 1, the mixture A + B/W is fed from vessel 1 to the top of a column 2 where it meets an ascending column of a second, immiscible, solvent which preferentially extracts A. The B-enriched mixture in solvent W leaves the foot of the column to return to vessel 1 while the A- enriched mixture in solvent S is fed to fractionating column 3 where it meets a descending stream of a reflux phase of A in solvent W. Stripping takes place to give a B-enriched mixture in solvent W which is fed to vessel 1, and an ascending solution of A in solvent S which is fed to column 4 where it meets solvent W to be stripped to give solvent S for feeding to column 2 and the reflux phase A/W, part of which is fed to column 3 and part taken off as product. Alternatively, part of the solution of A in solvent S, A/S, between columns 3 and 4 may be taken as product. An evaporator may be included between vessel 1 and the top of column 2 to remove part of the solvent for use as feed. Column 4 may be incorporated as the top portion of column 3, the product being withdrawn at the appropriate intermediate point. Column 3 may be incorporated as the top portion of column 2, Fig. 2, not shown. Successive treatments using different solvents for S may be employed to separate the components of a mixture.

Abstract: 1,182,351. Magnetically retained switches. S. SHIMADA. 24 Jan., 1967 [5 Feb., 1966; 25 Feb., 1966; 14 July, 1966; 14 Dec., 1966], No. 3573/67. Heading H1N. A switch which is held closed against spring bias by the attraction between a permanent magnet and a magnetic conductor has the magnetic conductor in series with its contacts and is opened on overload due to the reduction in the magnetic attraction. Low overloads cause heating of the conductor to reduce its permeability whilst heavy overloads directly reduce the magnetic attraction. In Fig. 1 a permanent magnet M is pivoted at 4 and is moved by sliding knob 3a. A magnetic conductor 14 moves with the magnet M to engage and disengage its contact 16 with a fixed contact 7. A tension spring 8 does not normally overcome the magnetic attraction between members M and 14 but when the attraction is reduced the spring opens the contacts. Arc interrupting ridges 100 are provided on the walls of the switch cover 2. Fig. 7 is a side view of a double-pole arrangement with an insulating magnet M attracted to conductors 14a, (14b) and contacts 6, 7 held closed by members 5 linked to the magnet M. The conductor 14 may be straight, U-shaped, V- shaped or formed by two connected discs (Fig. 11E, not shown) and may have conducting and magnetic sections. In Fig. 12A the conductor 14 attracts two magnets Ma, Mb each controlling a respective contact 6, 7 so that both contacts move when the magnets are released. The switch may be mounted in a plug-in cartridge of the type used to house a fuse (Fig. 15, not shown) or its contacts may be in a sealed envelope and operated by a movable magnet coupled to the magnet M (Fig. 16A, not shown). A switch of the type shown in Fig. 1 may be provided with a position indicator movable by the magnetic conductor, Figs. 17A and 17B (not shown).

Abstract: 123,729. Badin, R. E. Aug. 19, 1916, [Convention date]. Indicators actuated by pressure of head of liquid.-In apparatus particularly intended for indicating the liquid level in the petrol tanks of motor cars and aeroplanes, air is forced by a pump 1 into an open-ended pipe 4 dipping into the liquid in the tank 3 until it escapes from the pipe and bubbles up through the liquid, the air pressure, which is a measure of the head of liquid in the tank, being indicated by a gauge 5. The pump barrel 6, Fig. 2, is made in one piece with the pressure-gauge frame 7. , The plunger 12 is withdrawn against the compression of a spring 11, which, when the plunger rod 8 is released, returns the plunger so as to force air through an adjustable outlet 13 into a chamber 19, to which the air pipes are connected. The glass 32 is held in the frame by an elastic ring 33 driven into a conical groove in the frame and secured by white lead, shellac or cement. The pipe 4 may be enclosed in a perforated sheath so as to avoid fluctions of air pressure due to oscillations of the liquid around the pipe.

Abstract: 414,725. Variable speed gearing. BORGNA, G., 3, Via S. Giuseppe Pinerolo, Turin, Italy. Feb. 7, 1933, No. 3764. [Class 80 (ii).] In variable-speed gearing of the kind comprising a pair of co-operating pulleys having expansible V - grooves, one or both conical surfaces of which are formed by several conical rings 2, 2<1>, 3, 3<1> &c. relatively displaceable in an axial direction, the rear surfaces of the conical rings and the hub portions 16, 16<1> of a disc or discs 1, 1<1> supporting the rings are conical and face one another so that on axial movement of the supporting disc or discs relatively to a hub 6, 61 fixed or splined to the pulley shaft 10, pins or bolts 7, 7<1> guided in the hub slidably engage the said conical surfaces to effect axial displacement of the conical rings and hence vary the depth of the V-grooves. In Fig. 3, the two sides of the V- groove have relatively displaceable conical rings respectively 2, 3, 4 and 21, 31, 4<1>, the outer ones 2, 2<1> being bolted to supporting discs 1, 1<1> slidably keyed to the shaft 10. Hub parts 6, 6<1> which are bolted together have extensions 8, 8<1> in which the pins 7, 7<1> with their ends bevelled at 45‹ slide. The discs 1, 11 are moved axially by worm gearing 17, 42, ball thrust bearings being interposed between the discs and the worm wheels 42, which screw on to fixed bearing housings 41. Instead of worm gearing, sleeves corresponding to the worm wheels 42 are moved axially by levers joining the corresponding sleeves on the driving and driven shafts and pivoted intermediately. In a modification, Fig. 6, one side only of the V- grooves has conical rings and to enable the belt to move parallel to itself, the single conical surface 18 of the pulley on the driving shaft 10 and the supporting disc 21 of the pulley on the driven shaft 10<1> are axially fixed whilst the remaining halves of the two pulleys, i.e. the hub 19 of the driven pulley and the hub 16 of the driving pulley, are axially movable by means of sleeves 25 secured to them. The sleeves 25 are moved axially by sleeves 27 screwing into fixed bearings 28 and carrying chain wheels 24, operated through a chain 31 by a hand wheel 32. The position of least speed of the driven shaft is shown in Fig. 6. To increase this speed, the hand wheel is turned clockwise so that the sleeves 27 screw inwardly, the lower sleeve 25 being moved positively by means of a ball thrust bearing. The sleeves 25 are keyed to the shafts and disc 21 on the driven shaft has a spacing collar 35. For transmitting greater power several pairs of pulleys may be mounted on the two shafts and operated simultaneously by a single control such as the hand wheel 32. The pins 7, 7<1> may be inclined to the axes of the shafts and the inclinations of the conical surfaces on which they bear modified accordingly.
